Chevrolet Surburban LTZs that are used by guess who? Sector 7 of course.
Ram 1500s that are used by NASA
Maybach Landaulet that is owned by Agent Simmons
Another Maybach 62, and an Aston Martin Vantage owned by Patrick Dempsey's character
2 Cadillac XLRs. One is shortly seen in Chicago on fire, and then one is seen during the fight at the end.
Chrysler Concorde on fire
Hyundai Accent on fire.
Jaguar S-Type (I think) on fire

And there's a fragment of a new Chevrolet Aveo bumper on the ground in Chicago. I don't know if that should be listed.

Lots of cars "wrecked" (mostly CGI) not included.*SPOILER* A few burned Cadillacs including an Eldoado, several old pe-wrecked Benzes, a red Bmw 3-series(pre-wrecked) and also an 80s 7-series.There was a wrecked Impala.I think they flipped a gold Nissan--Altima or Maxima on the freeway scene. There was a blue Corolla also in the freeway sequence.Many,Many Crown Vics wrecked.Also, they destroyed a nice Ford Convertible from the late-60s (You knew theyd destroy some kind of classic).

Michael Bay is great director. Should we expect whole clips of earlier movies in upcoming ones?

Not really, I wish he would've included the Stunticons in the movie along with Motormaster(which is a 1987 Kenworth K100). That would have been interesting; Optimus Prime a Conventional Cab versus a Cabover.
